Application filed December 2, 1908. Serial No. l65,597.

To u?? ceo/1L if may concern.'

Be 1t known that I, CraiLLE C'rE, citizen of the United States, residing at 24; Rue de Naiarin, yParis, in the Republic of l" ance,

A further obect of the above invention is to construct the cylinder elements in sections and to insert a segment element between two of the adjacent sections to prevent the escape of the gas from the cylinders.

Other objects and advantages will appear from the following description with referto the accompanying drawings, wherein Figure-1 is a transverse vertical sectional View of anengine embodying my invention.

Fig. .2 is a longitudinal yertical section of the same.

Referring more specifically to the drawing wherein like'reference characters indicate like partsl throughout the different views, the letters-A and C designate the piston and pump cylinders respectively,

which are arranged in superposed positiony .on the. cank case D, wherein the driving shaft E is mounted together with the cranks e and e1.

The piston cylinder A, has two side walls 'al and (L: the inner wall thereof being offset a, while the pump cylinder,

A rests, has an anthe diameter of the lflanged portion thereof loeing substantially the same as the diameter of'the central portion of the piston cylinder. Formed integral with the piston cylinder A are the caps H which are `provided with apertures to receive these bolts or stays being screw threaded at their lower extremities as at g, whereby they are screwed into the threaded bores at its base as at upon which the cylinder formed in the crank case D. It will loe seen that in the assembling of the parts, the pump cylinder C is placed on the crank 'case D while the piston cylinder, the central Idiameterlof which is smaller than the correthe bolts on stays G,-

sponding diameter of the pump cylinder, is seated o'n the flanged end of the pump cylinder. Because the inner wall of the piston cylinder is ol'l'set at its base, an annular depression M is formed. This depression M, is adapted to receive' the steel segment l, which is, of course` placed in position when assembling the dill'crent parts. 'lhis steel segment l, insures the absoluto tightness of the pump and suppresses any escape of gas on account of its being made smaller' in diameter than the piston, so as to lit tightly around it. lVhen the above named parts are placed in their proper position, together with the piston K, which has its lower portion of a greater diameter than the, upper part thereof, the bars or bolts are`paz==sed through the caps H and are screwed into the bores in the crank case D, thus bringing all of the sections as tightly together as possible.

`The piston K is provided with a plurality of annular grooves,wherein a plu ality of packing` members or washers'L are secured.

Vhat I claim and for which I desire to secure Letters Patent is:-

l. In a combustion engine, the'combination with an engine cylinder having an annnla aperture at its base, of apump cylinder of larger diameter than, and in alinemcnt with said engine cylinder, a centering flange at the upper end of the pump cylinder in engagement with said aperture', a common piston for both cylinders built on two diameters, a crank shaft case below the pump cylinder; saidannular aperture, centering flange and the wall of the piston forming a packing chamber; a packing comvof a plurality of pump cylinders of larger diameter than, and in alincment respectively with said engine cylinders, a centering flange at the upper 'end of each-pump cyllso inder in .engagement with seid leperture,, e common piston for each pair of cylinders bui-lt on two diameters,'a crank shaft cese4 below each pump cylinder; seid annular aperture, centering flange and the Wall of the piston `forming a peeking chamber; e peeking comprising-annular met-al sections in said Chamber, said metal sections tting tightly 4around the piston, so as to prevent leakage' around it; `bolts for clamping toy gether 'said engine and pump cylinders and seid crank shaft ease, whereby on tightening Lemme Said boilts sei metelireim will be com pressed in said ehember'by gemeente@ flange to form e, tight joint betweeh Sel 25.5

engine and pump cylinders. z In testimony .whereof l have hereuntsel my hand inthe presence of two snbsmribine?.
